Remove Multidex usages
Since the min SDK is at least 21, it is no longer necessary to use the Multidex library.
See the following for more info: https://developer.android.com/build/multidex#mdex-on-l
I see the builds fail on my PR. Is there something I have to fix, or is it the same failures as on master?
Hi @MGaetan89. I have reviewed your PR, and you are right, we don't need multidex anymore, it's a legacy part that remained in our codebase for a long time. Currently we have some issues with the open source builds so they can't run on your PR. I ran our E2E tests for both our apps for the proposed changes on a different branch and they were successful, so I will merge your PR.
Thank you for your contribution.
